前些天发现了一个巨牛的人工智能学习网站,通俗易懂,风趣幽默,忍不住分享一下给大家。点击跳转到教程。
1. 场景,springcloud 学习工程中,把 feign 和 ribbon 工程 作为应用服务,纳入 hystrix-turbine 服务监控中。
2. feign 工程启动报错如下:
ClassNotFoundException:
com.netflix.hystrix.contrib.javanica.aop.aspectj.HystrixCommandAspect
3. 解决:
在 pom.xml 中加上依赖:
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-hystrix</artifactId></dependency>
此时, feign 完整依赖为:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.feign</groupId><artifactId>service-feign</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>service-feign</name><description>服务消费 feign 方式</description><parent><groupId>com.base</groupId><artifactId>base-config</artifactId><version>0.0.1-SNAPSHOT</version></parent><dependencies><!-- 开启 hystrix 监控 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-hystrix</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId></dependency></dependencies><repositories><repository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/milestone</url><snapshots><enabled>false</enabled></snapshots></repository></repositories></project>
4. 启动工程成功。
